Resumen:

In this work, the dynamic flexural behaviour of composite sandwich beams, with glass fibre/polyester face-sheets and foam core was analysed by a numerical model. This model was validated through several dynamic flexural tests.

This model was validated through several dynamic flexural tests. The contact force, absorbed energy, and maximum displacement in both face-sheets were analysed.[+][-]
